. LANTERN.

SPECIFICATION forming art tr Letters Patent No. 728,738, dated Ma 19,1903.

Application filed November 8, 1902. seen. No. 130.608. (No model-J inlanterns of that kind or class adapted for railway signaling; and theobject is to' provide a lamp or lantern of the kind named and for thepurposes stated wherebya clear signal may be changed to indicate anothercharacter of signal-such as danger, can-1 tion, and other designated ordetermined character prescribed by the rules of the road and thenrestored as desired to the original or primary condition.

The invention embodies a lantern comprising the usual constructions andequipments, a base-ring, a lifting expanding spring, and a coloredcylinder seated on the ring and adapted to be depressed and elevated,all as will be fully set forth and the novelty claimed particularly anddistinctly pointed out.

I have fully and clearly illustrated'my invention in the accompanyingdrawings, forming a part of this specification and wherein Figure 1 is aside elevation of a lantern equipped with my improvements, showing thecolored signal-cylinder elevated. Fig. 2

is a horizontal'section taken on the line 2 2 of Fig. 1, showing thearrangement of the parts. Fig. 3 is a central vertical section throughthe lantern, showing theaggroupment of the parts, with thelifting-spring expanded and the colored signal-cylinder in elevatedposition surrounding the lampfiame. Fig. it is a perspective View of thecolored signal-cylinder. tive view of the supporting-ring on which thecolored signal-cylinder seats.

In the drawings similar reference notations designate like parts in allof the illustrations.

Referring to the drawings, A designates the lantern-frame, comprisingvertically-arranged standards 1 in radial relation and formed withinwardly-extending knees 2. These standards are connected andstrengthened above the knees by wires 3, passed through them with theends cemented to.- gether, and at the base is a similar wire 4,

Fig. 5 is a perspec-:

which strengthens and binds the legs together. At the top of thestandards is secured a flanged ring 5,10 which is hinged the cover6,formed with a fine extension 7, perforated as usual to provide a draftfor the lamp. A spreader Sis located in the flue extension.

Asnap-catch 9 is secured to the cover 6,

which engages the flange on the ring 5 and locks the cover in closedposition. Between the knees 2 is arranged and secured the lampcylinder10. This consists of a metal cyliuder having open ends and of suchheight and diameter as may adapt it to receive and contain the lamp andto hold the base-flange of the chimney 11, the top of which is held inplace by a circular flange 12 on the inner face of the cover. 13designates the lamp of the usual make, having its bottom extended andformed with a vertical annular flange'14, which fits up around the lowerpart of the cylinder lOand is detach-ably held in position by theengagement of laterally-projecting lugs 15 on the cylinder with a slot16 and a spring-tongue 17 in a well-known manner. A carrying-bail 18 is.secured to the upper ends of opposite standards, as shown. Each and allofthese elements and parts hereto-v fore described are of well-knownconstruction, except that the lamp-cylinder 10 is preferably made longerthan usual to fully accommodate the improved appliances and partsinvolved in my invention, and also certain changes are made in thecylinder 10 for the same purpose, and these, with the other embodiedparts of the invention, I now proceed to describe.

l9.designates an expansive spiral spring disposedin the space betweenthe cylinder 10 and thelamp 13, as shown in Fig. 3 of the drawings, withthe lower coil secured in clips slots, so as to hold the springdepressed and the colored cylinder down in its lower position. Thecolored signal-cylinder, as here tofore mentioned, may be of anyselected color designed to publish a signal having a prescribed meaning.

The utilization of the improvements may be stated as follows: Normallythe white light is displayed and indicates a well-known signal; butshould a signal of other significance and meaning be required then alamp having a colored cylinder of the kind necessary is selected, thearms 26 are unlocked, and the spring moves the colored cylinder intoupper position and surrounding the white light, and a signal of theselected color is displayed. When the exigency has passed, the spring isdepressed, carrying with it the colored cylinder, and again the whitelight prevails.

The advantages attending the use of a lantern of the constructionspecified are several and important. Every trainman, switchman,

flagman, or other employee of a railway company whose duties require himto attend on the coming and going of trains is under present rgimeprovided with a red lantern or any other color indicative of danger orcanlion and at the same time is allowed to carry only one lantern, thesignal designation of which is stationary and unchangeable, while in theinstance of the invention he carries a lantern which can be changed toimpart either a clear signal or a danger indication. Its use alsomaterially reduces the expense in the stock of lanterns and saves incost of oil and labor of keeping the lanterns supplied.

Having thus fully described the invention, what is claimed as new is Ina signal-lantern, the combination with the lamp, having its bottomextended and formed with a vertical annular flange, of a lamp-cylinderformed with opposite vertical slots having bayonet extensions at theirbase, an expansive spring arranged between the lamp and thelamp-cylinder, a plate-ring secured to the upper coil of the ring formedwith diametrically opposite finger-pieces to slidingly engage in thevertical slots of the lamp-cylinder, and a colored signal-cylindermounted on the ring.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. MANLEY.
